Description

Lightweight RV toilet with all-plastic round bowl and gravity-flush. Designed for durability, easy installation in tight spaces (compact rear profile, 7-5/8" rough-in), and user comfort (soft-close seat, residential chair-height, quiet and powerful spray flush). Features DIY replaceable parts, tool-free ball seal replacement, and redesigned sealing with a sonic-welded water valve to prevent leaks and odor.
